Any help appreciated.

That minus sign on your last step is a trouble maker, as that will get you nowhere really.
from your 4th step its straight forward from there.
and you solve it like a quadratic equation:
so basically:
y= is either 2,1
thus x= 100, or 10 and log(x)= 2, or 1
Thanks to both for the quick replies.Originally Posted by Heinsbergrelatz
